The problem with these big part store chains is that the parts they recommend are not necessarily the best fit. I've been looking for a gas cap for my Monza (as many of you may know) and most of these store chains recommend the Stant locking gas cap shown below (about 3.75 inches wide?) for all years. I decided to go with the Stant part #10746 also shown below (4.25 inches wide) which is supposed to be a replacement for a Plymouth Volare but, as you can see, it fits like a glove.

I have enclosed a closer view of the gas cap. You'll notice how flush it sits to the body. It's a nice replacement gas cap and very easy to find.

(See attached images for following explanation)

Because this is a replacement for a Plymouth Volare, the handle will not sit completely horizontal when rotated into place (image 2A). What you may want to do (which is what I did with mine- image 2B) is take the handle apart (2 screws hold the valve to the handle) and redrill 2 new offsets on the valve plate. Once put back together it will thread into place pretty much like the original cap.
